To all whom i may @Lincei-m perforntion in the tup u onlo the journnl Beit known that I, TILLIAM T. Surfin, ot' by the compression nl' the nirbetween ilu?

My invention relates to au improvement in lubrieators, and moreparticularly to that class of lnbrientors employed in supplying nlubricant. in its nondiquid state to journals.

The object of my prfentl invention is to provide a lnhrientor whichshall eeononlize grease, keep the journals constantly luhricated, andwhich shall he Simple und inexpensive in construction.

'With these ends in view-:ny invention cousists in certain feature.u ol'construction und combinations of parts, will be hereinafter described,and pointed out in the claim.

A represents n cylindrical-shaped cup, prefernbly provided with arounded buse, ne Shown, and terminating :it its lower end in nscrew-threaded tap, a. An engulnrehnped nut-section, B, is convenientlyformed be tween the screw-mp a and the bottoni ol" the cup forconvenience in screwing the cup on and o thejournal-loox. The interiorol' the cup A is screw-threaded from top to bottoni, as shown at C, anda plunger, l), is provided with a male thread, d, on its edge, ndnptedto register with the thread C. the plunger i) is preferably concave,forming` a el'unnber, E. The plunger ills further providedwih a siem, e,on its upper side, nud n thumb-wheel, F, is formed on the stein l'orconveniently operating the plunger.

In operation the cup is filled with e lubricant in non-liquid forniwalu'loricnnt eoniposed of pnrafiine and neats-foot oil, for example-andthe plunger D is inserted in the The lower lnee ol' lower linee oi' theplunger und the upper `snri'nee ol' the grenen.
